I graduated high school in 1998 (that probably makes me the baby here) and we
still used US fluid ounces in our photo lab--even if, right across the hall,
we used liters and mL in chemistry. I for one preferred working everything
out in metric: I hated having to do all the fractions for mixing photo
chemicals in fluid ounces.
Because of the influence of our southern neighbours, I mix my chemistry in litres, buy my paper in meters, and sell prints by the inch.
